SAR Definition
Specific Absorption Rate (SAR) is defined as the time derivative (rate) of the incremental energy (dw) absorbed by
(dissipated in) an incremental mass (dm) contained in a volume element (dv) of a given density ( ρ ). It is also
defined as the rate of RF energy absorption per unit mass at a point in an absorbing body (see Figure 2).

SAR Mathematical Equation
SAR is expressed in units of Watts per kilogram (W/kg)
SAR measurement can be related to the electrical field in the tissue by
SAR =
Where:
σ
conductivity of the tissue (S/m)
ρ
mass density of the tissue (kg/m3)
RMS electric field strength (V/m)
*Note:
The primary factors that control rate of energy absorption were found to be the wavelength of the incident field in
relations to the dimensions and geometry of the irradiated organism, the orientation of the organism in relation to
the polarity of field vectors, the presence of reflecting surfaces, and whether conductive contact is made by the
organism with a ground plane〔2〕

4.1
DASY E-Field Probe System
The SAR measurements were conducted with the dosimetric probe (manufactured by SPEAG), designed in the
classical triangular configuration〔3〕and optimized for dosimetric evaluation. The probes is constructed using the
thick film technique; with printed resistive lines on ceramic substrates. The probe is equipped with an optical
multi-fiber line ending at the front of the probe tip. It is connected to the EOC box on the robot arm and provides an
automatic detection of the phantom surface. Half of the fibers are connected to a pulsed infrared transmitter, the
other half to a synchronized receiver. As the probe approaches the surface, the reflection from the surface
produces a coupling from the transmitting to the receiving fibers. This reflection increases first during the
approach, reaches maximum and then decreases. If the probe is flatly touching the surface, the coupling is zero.
The distance of the coupling maximum to the surface is independent of the surface reflectivity and largely
independent of the surface to probe angle. The DASY software reads the reflection during a software approach
and looks for the maximum using a 2nd order fitting. The approach is stopped when reaching the maximum.

E-Field Probe Calibration process
Dosimetric Assessment Procedure
Each E-Probe/Probe Amplifier combination has unique calibration parameters. A TEM cell calibration procedure is
conducted to determine the proper amplifier settings to enter in the probe parameters. The amplifier settings are
determined for a given frequency by subjecting the probe to a known E-field density (1 mW/cm2) using an RF
Signal generator, TEM cell, and RF Power Meter.
Free Space Assessment
The free space E-field from amplified probe outputs is determined in a test chamber. This calibration can be
performed in a TEM cell if the frequency is below 1 GHz and in a waveguide or other methodologies above 1 GHz
for free space.
For the free space calibration, the probe is placed in the volumetric center of the cavity and at the
proper orientation with the field.
The probe is rotated 360 degrees until the three channels show the maximum
reading. The power density readings equates to 1 mW/cm2.
Temperature Assessment
E-field temperature correlation calibration is performed in a flat phantom filled with the appropriate simulated head
tissue. The E-field in the medium correlates with the temperature rise in the dielectric medium. For temperature
correlation calibration a RF transparent thermistor-based temperature probe is used in conjunction with the E-field
probe.

Device Holder
The DASY device holder is constructed of low-loss POM material having the following dielectric parameters:
relative permittivity ε=3 and loss tangent δ=0.02. The amount of dielectric material has been reduced in the
closest vicinity of the device, since measurements have suggested that the influence of the clamp on the test
results could thus be lowered.

Data Storage and Evaluation
4.7.1
Data Storage
The DASY software stores the assessed data from the data acquisition electronics as raw data (in microvolt
readings from the probe sensors), together with all the necessary software parameters for the data evaluation
(probe calibration data, liquid parameters and device frequency and modulation data) in measurement files with
the extension DA4 or DA5. The post processing software evaluates the desired unit and format for output each
time the data is visualized or exported. This allows verification of the complete software setup even after the
measurement and allows correction of erroneous parameter settings. For example, if a measurement has been
performed with an incorrect crest factor parameter in the device setup, the parameter can be corrected afterwards
and the data can be reevaluated.
4.7.2
Data Evaluation
The DASY post processing software (SEMCAD) automatically executes the following procedures to calculate the
field units from the microvolt readings at the probe connector. The parameters used in the evaluation are stored in
the configuration modules of the software:
Probe parameters:
- Sensitivity
Normi, ai0, ai1, ai2
- Conversion factor
ConvFi
- Diode compression point
Device parameters: - Frequency
dcpi
- Crest factor
cf
Media parameters: - Conductivity
σ
- Density ρ
These parameters must be set correctly in the software. They can be found in the component documents or they
can be imported into the software from the configuration files issued for the DASY components. In the direct
measuring mode of the multimeter option, the parameters of the actual system setup are used. In the scan
visualization and export modes, the parameters stored in the corresponding document files are used.
The first step of the evaluation is a linearization of the filtered input signal to account for the compression
characteristics of the detector diode. The compensation depends on the input signal, the diode type and the
DC-transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the crest factor
of the signal must be known to correctly compensate for peak power. The formula for each channel can be given
as:
Vi  U i  U i2 

Tissue Simulating Liquids
The mixture is calibrated to obtain proper dielectric constant (permittivity) and conductivity of the tissue.
The dielectric parameters of the liquids were verified prior to the SAR evaluation using an 85070C Dielectric Probe
Kit and an E5071B Network Analyzer.
IEEE SCC-34/SC-2 in 1528 recommended Tissue Dielectric Parameters
The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in 1528 have been incorporated
in the following table. These head parameters are derived from planar layer models simulating the highest
expected SAR for the dielectric properties and tissue thickness variations in human head.
Other head and body
tissue parameters that have not been specified in 1528 are derived from the tissue dielectric parameters
computed from the 4-Cole-Cole equation and extrapolated according to the head parameter specified in 1528.

SAR Testing with RF Transmitters
6.1
SAR Testing with GSM/GPRS/EGPRS Transmitters
Configure the basestation to support GMSK and 8PSK call respectively, and set timeslot transmission for GMSK
GSM/GPRS and 8PSK EDGE. Measure and record power outputs for both modulations, that test is applicable.
6.2
SAR Testing with 802.11 Transmitters
SAR test reduction for 802.11 Wi-Fi transmission mode configurations are considered separately for DSSS and
OFDM. An initial test position is determined to reduce the number of tests required for certain exposure
configurations with multiple test positions. An initial test configuration is determined for each frequency band and
aggregated band according to maximum output power, channel bandwidth, wireless mode configurations and
other operating parameters to streamline the measurement requirements. For 2.4 GHz DSSS, either the initial test
position or DSSS procedure is applied to reduce the number of SAR tests; these are mutually exclusive. For
OFDM, an initial test position is only applicable to next to the ear, UMPC mini-tablet and hotspot mode
configurations, which is tested using the initial test configuration to facilitate test reduction. For other exposure
conditions with a fixed test position, SAR test reduction is determined using only the initial test configuration.
The multiple test positions require SAR measurements in head, hotspot mode or UMPC mini-tablet configurations
may be reduced according to the highest reported SAR determined using the initial test position(s) by applying the
DSSS or OFDM SAR measurement procedures in the required wireless mode test configuration(s). The initial test
position(s) is measured using the highest measured maximum output power channel in the required wireless
mode test configuration(s). When the reported SAR for the initial test position is:


≤ 0.4 W/kg, further SAR measurement is not required for the other test positions in that exposure configuration
and wireless mode combination within the frequency band or aggregated band. DSSS and OFDM configurations
are considered separately according to the required SAR procedures.
> 0.4 W/kg, SAR is repeated using the same wireless mode test configuration tested in the initial test position to
measure the subsequent next closet/smallest test separation distance and maximum coupling test position, on the
highest maximum output power channel, until the reported SAR is ≤ 0.8 W/kg or all required test positions are
tested.
 For subsequent test positions with equivalent test separation distance or when exposure is dominated by
coupling conditions, the position for maximum coupling condition should be tested.
 When it is unclear, all equivalent conditions must be tested.

For all positions/configurations tested using the initial test position and subsequent test positions, when the
reported SAR is > 0.8 W/kg, measure the SAR for these positions/configurations on the subsequent next highest
measured output power channel(s) until the reported SAR is ≤ 1.2 W/kg or all required test channels are
considered.
 The additional power measurements required for this step should be limited to those necessary for identifying
subsequent highest output power channels to apply the test reduction.

When the specified maximum output power is the same for both UNII 1 and UNII 2A, begin SAR measurements in
UNII 2A with the channel with the highest measured output power. If the reported SAR for UNII 2A is ≤ 1.2 W/kg,
SAR is not required for UNII 1; otherwise treat the remaining bands separately and test them independently for
SAR.
When the specified maximum output power is different between UNII 1 and UNII 2A, begin SAR with the band that
has the higher specified maximum output. If the highest reported SAR for the band with the highest specified
power is ≤ 1.2 W/kg, testing for the band with the lower specified output power is not required; otherwise test the
remaining bands independently for SAR.

To determine the initial test position, Area Scans were performed to determine the position with the Maximum
Value of SAR (measured). The position that produced the highest Maximum Value of SAR is considered the worst
case position; thus used as the initial test position.

SAR to peak location separation ratio (SPLSR)
When the sum of SAR is larger than the limit, SAR test exclusion is determined by the SAR to peak location
separation ratio. The ratio is determined by (SAR1 + SAR2)^1.5/Ri, rounded to two decimal digits, and must be ≤
0.04 for all antenna pairs in the configuration to qualify for 1-g SAR test exclusion.
All of sum of SAR < 1.6 W/kg, therefore SPLSR is not required.

SAR test reduction according to KDB
General:
 The test data reported are the worst-case SAR value with the position set in a typical configuration.
Test procedures used were according to FCC, Supplement C [June 2001], IEEE1528-2013.
 All modes of operation were investigated, and worst-case results are reported.
 Tissue parameters and temperatures are listed on the SAR plots.
 Batteries are fully charged for all readings.
 When the Channel's SAR 1 g of maximum conducted power is > 0.8 mW/g, low, middle and high channel are
supposed to be tested.
KDB 447498:
 The test data reported are the worst-case SAR value with the position set in a typical configuration.
Test procedures used were according to IEEE1528-2013.
KDB 865664:

Repeated measurement is not required when the original highest measured SAR is < 0.80 W/kg.

When the original highest measured SAR is ≥ 0.80 W/kg, repeat that measurement once.

Perform a second repeated measurement only if the ratio of largest to smallest SAR for the original and first
repeated measurements is > 1.20 or when the original or repeated measurement is ≥ 1.45 W/kg.

Perform a third repeated measurement only if the original, first or second repeated measurement is ≥ 1.5
W/kg and the ratio of largest to smallest SAR for the original, first and second repeated measurements is >
1.20.
KDB 941225:
 In order to qualify for the above test reduction, the maximum burst-averaged output power for each mode
(GMS/GPRS/EDGE) and the corresponding multi-slot class must be clearly identified in the SAR report for
each frequency band.We perform worst case SAR with maximum time-average power on
GMS/GPRS/EDGE mode.

Validation Summary
Per FCC KDB 865664 D02 v01r02, SAR system validation status should be documented to confirm measurement
accuracy. The SAR systems (including SAR probes, system components and software versions) used for this
device were validated against its performance specifications prior to the SAR measurements. Reference dipoles
were used with the required tissue- equivalent media for system validation, according to the procedures outlined
in IEEE 1528-2013 and FCC KDB 865664 D01v01r04. Since SAR probe calibrations are frequency dependent,
each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration
point, using the system that normally operates with the probe for routine SAR measurements and according to the
required tissue-equivalent media.

Measurement Uncertainty
Measurement uncertainties in SAR measurements are difficult to quantify due to several variables including
biological, physiological, and environmental. However, we estimate the measurement uncertainties in SAR1 g to be
less than ±21.88 % for 300 MHz ~3 GHz and 3 GHz ~ 6 GHz ±25.37 %〔8〕.
According to Std. C95.3〔9〕, the overall uncertainties are difficult to assess and will vary with the type of meter and
usage situation. However, accuracy’s of
 1 to 3 dB can be expected in practice, with greater uncertainties in
near-field situations and at higher frequencies (shorter wavelengths), or areas where large reflecting objects are
present. Under optimum measurement conditions, SAR measurement uncertainties of at least
 2 dB can be
expected.

Measurement Procedure
The measurement procedures are as follows:
1.
For WLAN function, engineering testing software installed on Notebook can provide continuous transmitting
2.
Measure output power through RF cable and power meter
signal.
3.
Set scan area, grid size and other setting on the DASY software
4.
Find out the largest SAR result on these testing positions of each band
5.
Measure SAR results for other channels in worst SAR testing position if the SAR of highest power channel is
larger than 0.8 W/kg
According to the test standard, the recommended procedure for assessing the peak spatial-average
SAR value consists of the following steps:
10.1
1.
Power reference measurement
2.
Area scan
3.
Zoom scan
4.
Power drift measurement
Spatial Peak SAR Evaluation
The procedure for spatial peak SAR evaluation has been implemented according to the test standard. It can be
conducted for 1 g and 10 g, as well as for user-specific masses. The DASY software includes all numerical
procedures necessary to evaluate the spatial peak SAR value.
The base for the evaluation is a "cube" measurement. The measured volume must include the 1 g and 10 g cubes
with the highest averaged SAR values. For that purpose, the center of the measured volume is aligned to the
interpolated peak SAR value of a previously performed area scan.
The entire evaluation of the spatial peak values is performed within the post-processing engine (SEMCAD). The
system always gives the maximum values for the 1 g and 10 g cubes. The algorithm to find the cube with highest
averaged SAR is divided into the following stages
1.
Extraction of the measured data (grid and values) from the Zoom Scan
2.
Calculation of the SAR value at every measurement point based on all stored data (A/D values and
3.
Generation of a high-resolution mesh within the measured volume
4.
Interpolation of all measured values form the measurement grid to the high-resolution grid
5.
Extrapolation of the entire 3-D field distribution to the phantom surface over the distance from sensor to
6.

Area & Zoom Scan Procedures
First Area Scan is used to locate the approximate location(s) of the local peak SAR value(s). The measurement
grid within an Area Scan is defined by the grid extent, grid step size and grid offset. Next, in order to determine the
EM field distribution in a three-dimensional spatial extension, Zoom Scan is required. The Zoom Scan measures
points and step size follow as below. The Zoom Scan is performed around the highest E-field value to determine
the averaged SAR-distribution over 10 g.

Volume Scan Procedures
The volume scan is used for assess overlapping SAR distributions for antennas transmitting in different frequency
bands. It is equivalent to an oversized zoom scan used in standalone measurements. The measurement volume
will be used to enclose all the simultaneous transmitting antennas. For antennas transmitting simultaneously in
different frequency bands, the volume scan is measured separately in each frequency band. In order to sum
correctly to compute the 1 g aggregate SAR, the DUT remain in the same test position for all measurements and
all volume scan use the same spatial resolution and grid spacing. When all volume scan were completed, the
software, SEMCAD postprocessor can combine and subsequently superpose these measurement data to
calculating the multiband SAR.
10.4
SAR Averaged Methods
In DASY, the interpolation and extrapolation are both based on the modified Quadratic Shepard’s method. The
interpolation scheme combines a least-square fitted function method and a weighted average method which are
the two basic types of computational interpolation and approximation. Extrapolation routines are used to obtain
SAR values between the lowest measurement points and the inner phantom surface. The extrapolation distance
is determined by the surface detection distance and the probe sensor offset. The uncertainty increases with the
extrapolation distance. To keep the uncertainty within 1% for the 1 g and 10 g cubes, the extrapolation distance
should not be larger than 5 mm.
10.5
Power Drift Monitoring
All SAR testing is under the DUT install full charged battery and transmit maximum output power. In DASY
measurement software, the power reference measurement and power drift measurement procedures are used for
monitoring the power drift of DUT during SAR test. Both these procedures measure the field at a specified
reference position before and after the SAR testing. The software will calculate the field difference in dB. If the
power drift more than 5 %, the SAR will be retested.

11.1
This sample only supports 1slot.
When the WWAN band channel's reported SAR1g of the position is > 0.8 W/kg, low, middle and high channel
are supposed to be tested.
Require the middle channel to be tested first, if the maximum output power variation across the required test
channels is > ½ dB, instead of the middle channel, the highest output power channel must be used.
The device is designed for WWAN and WLAN and cannot be transmitted simultaneously, hence combined
SAR is not required.
Also mention the reason for N/A of WLAN, as per KDB 447498 D01 v06 4.3.1, as a separate note.
